An interesting article by Peter Kankowski :

JJ,

Yes, I believe that. You have many calls to a procedure, but that procedure only has 1 ret (maybe more than 1 with conditional early exits). Note the stats are for the code itself, not a profile of the execution of the code.

Dave,
I overlooked the obvious. Thanks for putting me back on track :biggrin:

API functions are probably used ~5:1 over local PROC's

The way software is done now days.. there are many proc calls with just as many crashes, without rets...
Not surprising  :P
